CARTON FILLING AND WEIGHING MACHINE.

Specification of Letters Patent.

Patented Apr. 9, 1918.

Application filed August 29, 1917. Serial No. 188,841.

To all whom it may concern:

Be it known that I, CHARLIE Rem), a citizen of the United- States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Carton Filling and Weighing Machine, of whichthe following is a specification.

This invention relates particularly to machines adapted to the purposeof filling cartons or other packages with accurately weighed charges ofpulverulent or granular material; and the primary object of theinvention is to provide an improved machine of high capacity, which willoperate with accuracy and certainty,and which possesses greatdurability.

To facilitate an understanding of the de tailed description of theinvention, which follows, it may be stated at the outset that in thepreferred embodiment there are employed: a continuously operatingendless delivery-conveyer leading to the machine; an endless discharge'conve or parallel therewith, but extending furt or into the machine; aninterposed endless service-conveyer having a step by-step movement; ascale having a load-platform or scale-pan interposed between the serviceconveyer and the discharge-conveyer; a pair of partialcharge fillingdevices disposed above the service-conveyer, each operating, whendesired, to deliver a partial charge to the carton under it, so thateach carton receives a ortion of its charge from each of said filllngdevices, the aggregate weight of the partial charges, however, beingsomewhat less than the desired weight of material for the completecharge; a pair of transversely acting carton-transferrers, one of whichoper ates to deliver a carton from the deliverycOnVeyer totheservice-conveyer, while the other operates to deliver a carton fromthe rear end of the service conveyer to the scalepan and at .the sametime to shove the filled and weighed carton from the scale-pan to thedischarge-conveyer; driving mechanism for the carton-transferring means,whichserves also to operate the partial-charge filling devices, salddriving mechanism being controlled by a scale-controlled controllingdevice and also controlled by a controlling device timed with thedriving mechanism of the service-conveyer; and driving mechanism for theservice-conveyer adapted to intermittently actuate the same or give tothe service conveyer a step-by-step movement,

said last-named driving mechanism having associated therewith timed withthe movement of the service conveyer and serving to control theoperation of the driving mechanism for the cartontransfcrrers and thepartial-charge filling devices.

Thus, the transferring devices and the partial-charge filling devicescan operate only after the service conveyer has stopped and the scalehas been tripped in the weighing operation; and the service-conveyer canbe advanced only after the completion of the operation of thetransferring devices and the partial-charge filling devices.

The invention is illustrated in the preferred embodiment in theaccompanying drawings, in which- Figure 1 represents a side elevationalview,

(Figs. Land 11) means for actuating said fillingdevices, said means N being actuated b "the cam J and P, a final-feeddischarge-c ute disposed above the scalean and-receivin its supply froma hopper through whic extends a screw-conveyer P (Fig. 3), whosevertical shaft P is actuated by a horizontal shaft P, upon which ismounted a loose pulle P, which is adapted to be connected wit the shaftP* by means of a clutch P", which is actuated by scale-controlledmechanism P.-

are geared to longitudinal shafts 5, the shafts 5 being connected by asprocket-- chain 5'. One of the shafts 5 is fitted with a crank 5. Itwill be understood that there arefour of the vertical screws 5 which suport the conveyer frame. B, and that by t e mechanism described screws 5will be simultaneously turned"'td' raise or lower the frame B, as thecase may be. The purpose of providing for raising or lowermg theconveyer-frame is to' adapt the machine to different-sized cartons, itbeing necessary that the cartons shall pass beneath the partial-chargefilling devlces N, N and also beneath the final-feed discharge-chute P.

The conveyer-supporting frame B comprises, in addition to the cross-bars4, 4 at the ends of the machine, longitudinal bars 6, 6, forming therunway of the service conveyer E (Fig. 3), and longitudinal bars 7,forming the runway of the conveyer D. Said longitudinal bars aresuitably secured to brackets mounted on the cross-bars 4.

The delivery-conveyer O, which feeds the cartons to the machine, maycomprise an endless belt 8, whose rear end is mounted on a pulley 9,journaled in brackets 10, which extend rearwardly from the frontcross-bar 4 of the frame B; and supporting bars. 11 for the belt. Thebarswhich extend away from the machine may be pivotally supported, sothat vertical adjustment of the conveyer supporting frame B will bepermitted. Cartons R are shown on the belt 8 and at proper locations inthe machine.

The discharge-conveyer D comprises the longitudinal bars 7, forming apart of the conveyer-supporting frame B; an endless belt 12, having itsrear end supported on a roller 13, which is mounted on a shaft 14 inalinement with the shaft P, the shaft 14 and the sleeve I being drivenin opposite directions by means of bevel-gears located on' oppositesides, of a bevel-gear 15 on the vertical shaft I sothat the conveyers Dand E run in opposite directions; a roll 16 near the rear end of themachine, beneath which the top portion of the belt 12 passesi and aroller 17 journaled in hangers epending from the front crossbar 4 of theframe B, which supports or steadies the lower portion of the belt 12.

The shafts I and 14 are carried by rearwardly extending brackets 18mounted on the rear cross-bar 4 of the frame B.

The service-conveyer E, which is intermittently actuated, and whichserves to advance the cartons step-by-step and position them seriatimbeneath the partial-charge filling-devices N and N comprises (Figs. 4and 5), in addition to the longitudinal bars 6 which form a part of theconveyersupporting frame B, a pair of endless chains 19, mounted onfront sprocket-wheels 2O and rear sprocket-wheels 21, the latter pair ofsprocket-wheels being mounted on the sleeve or tubular shaft I of thedriving mechanism for the conveyer E; cartonengaging members, or blades,22, mounted upon the chains at intervals corresponding to the spacing ofthe filling devices N and N as well as with the space between themounted in adjustable bearings, enabling the sprocket-chains 19 to bemade taut. This feature is not illustrated in detail, but any suitableadjusting means may be employed.

Extending transversely across the frame 1 of themachine and sultablymounted on the frame is a pair of rods 27 (Figs. 1 and 5). These rodssupport a pair of guidebars 28, correspondin with the serviceconveyer E,and a pair of guide-bars 29, corresponding with the discharge-conveyerD. The set of guide-bars 28 is supported by threaded vertical rods orhangers 30, on which the brackets which carry the bars 28 are verticallyadjustable. The rods 30 depend from adjustable sleeves 31, mounted onthe cross-rods or shafts 27, so that the bars 28 may be adjusted towardor from each other by moving the collars or sleeves 31.

The guide-bars 29 are similarly adjustable vertically on threaded rods32, which depend from collars 33, adjustably mounted on the transversebars or rods 27. The purpose isto adapt the guides to cartons of varyingsizes. 1 The cartons R are delivered by the belt 8 against a stop 34(Fig. 4), which is so positioned that the rearmost carton on the belt 8will. be disposed opposite the cartontransferrer G, which operates infront of the feed-chute of the first filling device N. The carton-guides23 and 28, which are nearest the delivery conveyer C, are cut away, asindicated at 35, to admit the cartons to the service-conveyer E. One ofthe carton-guides 29 associated with the discharge-conveyer D is shorterthan the other, and is bent toward the conveyer E, as indicated at 36,so that the weighed package will be admitted to the conveyer D andguided thereonto.

The scale F comprises, in addition to the scale-pan F a pair of verticalhanger-bars 37 upon which the scale-pan is supported, a head or yoke 38,carrying the bars 37 (Fig. 14), the arms of the member 38 beingsupported on knife-edges 39, carried by the short" arm of the scale-beam40, a base or scale-support 41 carried by bars 42, which constitute achair, or braced-sup ort, firmly mounted on the main frame K (Figs. 1and 14) knife-edges 43, carried by the mp port 41 and on which thescale-beam is placed; and a weight 44 suspended by a rod 45 from thefree end of the scale-beam.

.The support 41 embraces the lower end vided with a sliding valve orclosure 46,

which is actuated by a bell-crank lever 47, mounted on a pivot 48, theshort arm 47 of said lever having connected therewith a spring 49, whoseupper end is secured to a bracket 50 carried by one of the longitudinalmembers of the frame A. The pivot 48 is carried by a bracket 51, whichis mounted on one -of the longitudinal members of the frame A. For thepurpose of holding the slide or valve 46 in the open position, thebell-crank lever 47 is equipped with an additional short-arm 47*, withwhich is connecteda link 52, which has pivotal connection at 53 with onearm of a latch-controlled lever 54. The lever 54 is mounted on arockshaft 55, carried by a bracket 56 mounted on the main frame. Theupper end of the lever 54 is equipped with a short arm carrying a roller57 a apted to engage thelatch-lever. The upper end of the lever 54 isalso equipped with aroller 58, adapted to be engaged by one arm 59 of abell-crank lever which is j ournaled on the shaft 55, the other arm, 59,

being pivotally connected with a cam-actuated vertical bar 60, which isadapted to be raised at intervals by means of a cam 61 (Fig. 3) mountedon the shaft J. The roller 57 with which the lever 54 is equipped isadapted to engage the horizontal arm 62 of a bell-crank latch-lever,which is pivotally supported at 63 and'has an upwardly extendingv arm62, which has its upper end provided with a laterally extending catch62*. The catch 62 is adapted to engage a notch of a latch-member 64which is pivotally mounted at 65 on a stationary support, which may beformed integrally with or carried by the member 41.

The end of the scale-beam is equipped with an upwardly extendingprojection or finger 66, which is adapted to engage the extremity 64" ofthe latch-lever 64, so that when the scale is tipped, the member 66 willcause the member 64 to release the bell-crank latch-lever comprising thearms 62 and 62", thereby releasing the lever 54 and enabling the spring49 to close the slide 46. The

- parts are restored to the latched position uring the operation of theshaft J which causes the cam '61 to elevate the member 60* by and rotatethe rock-lever comprising the arms 59 and 59. In this movement, the arm59 engages the roller 58 and forces the upper end of the lever 54inwardly until the roller 57 engages amotch 67 with which the long arm62- of the bell-crank latch-lever is provided. It will be noted that thepivot 53 is only slightly out of alinement with the pivot 55 and thepivot connecting the link. 52 to the arm 47". Thus, a toggle-jointeffect is gained, so that the restraining lever 54, which holds thebell-crank lever 47 in restraint, will be held easily by the latchmechanism described.

, The slide 46 is connected with a crosshead 68, which has a cam 68adapted to engage a laterally-extending arm 69, with which therock-shaft K is equipped, so that when the slide 46 is thrown to theclosed position, the rock-shaft K will be rocked so as to depress thelink K and release the deg K (Fig. 7) from the locking position, so thatthe shaft J will be actuated so as to operate the transferring devicesand the partial-charge filling devices N and N The screw-conveyer orpositive feed device P as has been pointed out, is actuated by the shaftP when the continuously running pulley P is connected, b the clutch P,to the shaft P. The clutch is shifted by a lever 70 forming a part ofthe clutch-control P. The lever 70 is mounted on a pivot 71, carried bya bracket 72 projecting laterally from the main frame. A spring 73 tendsto actuate the lever 70 in a direction to disengage the clutch. Thelower end of the lever is held outwardly, against the force of thespring 73, by a toggle-link device, comprising links 74 and, 75, whichare ivotally connected at 76. The outer on of the link 74 is connected bthe pivot 77 t0 the lower end of the lever 0;. and the inner end of thelink is connected, bythe pivot 78, to a stationary part. The link 60 isequipped with an upward extension 60', which is provided at its upperend with a roller adapted to strike the toggle-joint when the member 60is elevated by the cam 61, thus restoring the parts to the positionshown in Fig. 14,'in which movement the clutch P is thrown intooperative engagement. The toggle-links 74 and 75 are broken downwardlyby means of a bell-crank lever supported on a pivot 79, carried by astationary member and comprising a camactuated arm 79 and an arm 79brokenl in Fig. 14), which is adapted to strike t e toggle-links 74 and75 and depress them., For this purpose, the arm 79" is equipped. with aprojection fitted with a of the links 74 and 75 at the joint 76.

free end of the arm 79' is equipped with 'a roller 79, which is adaptedto be engaged a cam 68 with'whlch the head 68 is provided. Thus, whenthe slide or closure 46 7 is moved into position to close the lower endof the'chute P, the bell-crank lever comprising arms 7 9 and 79 will beactuated to depress the roller 7 9, break the to gle-joint 74 and 75downward, and permit e spring 73 J (shown 1 to actuate the lever '70 anddisengage the clutch P Asshown in Fig. 14, the lower end of the lever 54is prevented from swinging inwardly too far by means of an adjustablestop 80, carried by a stationary arm 81.

The scale-pan F is located sl ghtly below the plane of the upper side ofthe conveyer E, and slightly above the upper side of the conveyer-belt12, so that in the operation of the carton-transferring device G the'cartons will slide freely from the service-conveyer E to the scale-pan,and from the scalepan to the discharge-conveyer D. The scalepancomprises bars 82 fixedl secured to a threaded bolt 83, which extendthrough slots 84, with which the hangers 37 are provided.

The bolt 83 is firmly clamped to the bars 37 by means of clamp-nuts, aswill be understood from Figs. 4 and 14. By the means described, thescale-pan F may be adjusted vertically to correspond with the adjustmentof the conveyer-supporting frame B in adapting the machine to varyingsizes of cartons.

The carton-transferring devices comprise the pushers G and G and theactuating mechanism G Each of said pushers is carried by a stem 85 (Fig.4), which is adjustably mounted in a slide 86 (Fig.- 5),; which isactuated through the medium of a link 87 and an arm 88. The arms 88 arefixedly secured to a rock-shaft 89, which extends longitudinally of theframe, as shown in Fig. 1. Fixedly secured to the rock-shaft 89 is anarm 90, which is connected by' a link 91 to a slide-bar 92, actuated bythe camwheel J The cam-wheel J is provided with an annular groove 93which is eccentric to the shaft J, as shown in Fig. 6. In the groove 93moves a roller 94, which serves to actuate the slide-arm 92, shown inFig. 1. This kind of a movement is not new per are. It is illustrated,for instance, in my Patent No. 1 ,140.915, granted May 25, 1915 (seeFig.

10 of said patent)- It readilv will be understood that when the slide 92is reciprocated vertically by the cam J", the pushers G and G will besimultaneously reciprocated. The pusher G is set farther inwardly, ofcourse, than is the pusher G, as will be understood from Fig. 4.

' The main drive-shaft Hof the machine is actuated, as has been stated,by the continu- .ously running sprocket-wheel H -when the the shaft 1"continuously and also driving the shaft 14, which actuates thedischargeconveyer D continuous] The clutch I (see Figs. 4* and 6)comprises a wheel 95 secured to and adapted to actuate the sleeve 1 aratchet-wheel 96, secured to the shaft 1 and a pawl 97, supported on apivot 98, carried by the wheel 95. A spring 99 tends to throw the hookof the pawl into engagement with the ratchet. \Vhen this occurs, thewheel 95 will turn and rotate the sleeve I one revolution, thusadvancing the service-conveyer E one step.

When the wheel 95 completes its revolutlon, the projecting finger ortail-piece of the pawl is engaged y a hook 100, forming a part of alever 101. This constitutes a por-' tion of the cam-controlled mechanismM, which has a link 102 of adjustable length connecting the inner arm ofthe lever 101 with a bell-crank lever 103, one of whose arms is equippedwith a roller, which is adapted to be actuated by the cam M carried .bythe cam-wheel J The pivotal portion 103 of the bell-crank lever 103 isin the form of a sleeve or tubular rock-shaft, which is journaled uponthe rock-shaft of the mechanism about to be described. The dog L (whichis one of the dogs controlling the clutch J") is controlled by a cam104, which is mounted on or may. be formed integrally with the wheel 95(Fig. 7). This control is effected through the medium of the mechanismL, which comprises a cam-lever 105, mounted on the bracket 106 whichsupports the lever 101; an adjustable link 107 connecting the inner orfront end of the lever 105 to one arm 108 of a bell-crank lever, whoserock-shaft 109 supports the'sleeve 103. The other end of the rock-shaft109 is equipped with an arm 110, which is connected by the link 111 tothe bell-crank dog L.

The clutch J will be understood from Figs. 7, 12 and 13. The clutchproper is not novel. being illustrated in detail in mv Patent No.1,126,083, granted Jan. 26," 1915.

arm 113 fitted with a spring 114. The spring 114bears against an arm115, which 1s secured to a rocking clutch-pin 116, whlch is journaled inthe member 112, and which has a semi-cylindrical portion 116, whichprojects within an annular flange 117 with which the sprocket-wheel J 2is equipped, this flange being provided with a series of semicircularrecesses 118. When the dogs K and L are free from engagement with thearm 115, the spring 114 will actuate Sald. arm,v

rotate the pin 116 and cause the clutch portion 116" to engage one ofthe recesses 118, as shown in Fig. 13. Thus, the shaft J Wlll. turnthrough one revolution. when the arm 115will again engage the dogs andrelease the clu ch. V r

In Fig.4, the point Y is the point where the carton is fed onto theservice-conveyer; the point Y indicates the position of a carto disposedlow th p r l h s ed I and N Each of the filling devices N and N is ofthe construction shown in Fig. 11. There is a hopper 119, which mayserve for both filling devices, in which case it is in the form of anelongated hopper,- as appears from Fig. 1. This hopper is provided witha discharge passage 120 for each filling device, beneath which islocated a pivotally mounted chute or open-ended measure 121. The chutesor measures 121 are mounted on a rock-shaft 122, equipped with anactuatin arm 123, which is connected by a link 12% with a rock-lever125, which constitute a part of the actuating mechanism N. Therock-lever 125 has one arm connected to a link 126, whose lower end isconnected with a cam-lever 127 (Figs. 1 and 4),.which has its rear endsupported on a pivot 128 and its intermediate portion engaging the cam Jwhich is mounted on the shaft J When the shaft J rotates, it actuatesthe carton-transferrers and shifts the chutes 121 from the filling orcharge-accumulating position shown .m Fig. 11 to the discharge position,and then returns them to the position shown in Fig. 11 The lower ends ofthe measures 121 are adapted to swin over dischargechutes 129, beneathwhic the cartons are positioned when the service-conveyer is at rest.The chutes 129 are surmounted by plates 130, whose upper surfaces are ofthe shape of an arc.of a cylinder. The lates 130 are provided withpassages 131 an with extensions 132, forming bottoms for the measureswhen the are win the position shown in Fig. 11. he upper endsof themeasures are provided with part cylindrical extensions 121' adapted toclose the chutes 120, and the chutes 120 are provided with curvedlateral extensions 120, which close the upper ends of the measures 121when they are moved to the discharge position.

The partial charges accumulate in the measures 121, while theserviceconveyer is 1n operation; and after the service-conveyer stops,the operation of the transferring de-.

. vices and the actuation of the measures 121 occurs. The discharge fromthe measures .to 'the cartonsis quickly effected, and the measures arereturned to the charge-accumulating position before the service-conveyeris again'actuated.

Referrin to Figs. 8, 10, the 10:. 'tudinal bars 6, which form a part ofthe also form a part of the service-conveyer E. Provision 1s made at thepoint or stat on Y ame B,

for supporting the carton clear of the chains 19 to facilitate transferof the cartons from the conveyer E to the scale-pan. For this purpose,the longitudinal bars 6 of the conplate 135 has an inclined extension135,

whose free end extends below the level of the chains 19, so that thecarton will ride up the incline and be positioned on the plate 135. Thebars 22 attached to the chains 119 and ushers 22 are mounted ontransverse sufficiently elevated to clear the plate 135.

The longitudinal bar 6 which is adjacent the scale-pan F is alsoequippedwith an angle 136, whose horizontal flange 136? is substantially flushwith the plate ,,135, so that the carton will ride over the flange 136while being moved onto the scale-pan. Thus, the conveyer-chains arebridged by plates upon which the carton rests and slides 1n thetransverse movement.

The conveyer E is likewise e uipped with bridge-plates at the point Y, ware the cartons are de sited on the service conveyer.

The sea e is steadied against swaying movement by means of links 137(Fig. 3), one of which is pivotally connected with a bracket 138depending from one of the side members of the main frame. No novelty isclaimed for this feature.

. As shown in Fig. 3, the shaft J1, which ushers and the measures, s acam J" which actuates a actuates the equipped wit steadylng device forthe scale, and with a.

machine.

In Fig. 1, the rock-shaft K, which is controlled by the scale-beam andwhich is actuated by the closure for the chute P, is shown equipped withan arm 145 bearing a counter balance weight 146.

The machine operates as follows:

- The shaft H rotates continuously and drives the shaft I continuouslyand also drives the gear J continuously. The endless delivery-conveyer Cand the endless discharge conveyer D may connect with a cartonopeningand sealing machine (not shown). Such a machine will operate to opencartons and seal the lower ends thereof and deposit the cartons with the0 en end up on the delivery belt 8. The filed and weighed cartons willbe returned to the sealing machine by the conveyer D, and

' opening and sealing machine.

Assuming cartons R to be in the machine in the positions indicated, themachine will operate automatically, it being understood that in firstsetting the machine in motion, the' cartons arriving at the point Y mustbe sufliciently filled preliminarily to effect the tripping of the scalewhen the carton receives the final-feed from the dischargechute P;otherwise, it will be necessary to trip the machine by hand a few times,until the regular operation is established. Thereafter, each cartonarriving at the point Y (Fig. 4) receives something less than ahalfcharge; and when it arrives at the oint Y it receives something lessthan a hal -charge, the aggregate amount being slightly less than thatnecessary to trip the scale.

After the transferring devices have operated, which is effected in onecomplete revolution of the shaft J during which period the measures 121(Fig. 11) have been swun to the discharge position and then returned tothe charge-accumulating position, the cam M on the wheel J operates themechanism M (Fig. 6) and clutches the tubular actuating shaft I of theconveyer E to the shaft I. This causes the cartons to be advanced onestep. Upon the completion of the revolution of the tubular shaft I, thecam 104,

carried by the wheel 95 (Fig. 7?] actuates the mechanism L and releasest e dog L, which controls the clutch J When sulficient material is fedfrom the chute P to give the requisite weightto the package on thescale-pan, the scale-beam 0 rates,

releasing the compounded latch members.

the slide-actuatin lever 47 (Fig. 14). The slide 46 is then orced to theclosing position; and in this movement the cam 68 operates therock-shaft K and releases the dog- K, which controls the clutch J thusthrowing into 0 eration the shaft J which actuates the caron-transferring devices, the measure-actuating mechanism, thescalesteadying device 139, and the scale-lock controlling means 142.Also, when the slide 46 is moved to close the lower end' of the chute P,the cam 68 operates the bell-crank lever comprising the arms 79 and 7 9,thus releasing the clutch P and' throwing out of operation the positivematerial-feeding device P with which the chute P is equipped. When theshaft J completes its revolution, the hook-latch-lever 101 of themechanism M is released .topermit the clutch I to be again thrown intooperative engagement to advance the conveyer E another step. Referringto Fig. 7, it should be explained that the cam-roller of the lever I 105travels on the periphery of the disk or wheel 95 after leaving the cam104, so that the dog L will be held in the locking position, that is, inthe position of holding the clutch J 3 1n the released or inoperativeposition until the conveyer E has completed its step, whereupon the cam104 throws the dog L away from the clutch-restraining pos1t1on.

It may be stated here that the mechanism L is equipped with a spring147, which serves to hold the lever 105 in contact with its cam; and themechanism M is equipped with a spring 148, which tends to throw thelever 101 into position to disengage the pawl 97 from the ratchet-wheel96.

The horizontal frame or platform B, which supports the conveyers, may beadjusted vertically to accommodate the machine to cartons of varyingsizes; and the connecting rods 102 and 107 of the mechanisms M and M maybe adjusted to correspond with the adjustment of the skeleton platformB. The carton-guides may be adjusted to correspond with the varyingsizes claims should be construed as broadly as permissible in view ofthe prior art.
